People spend their 90% of time in life indoors and this tends to deprive them of quality air if there is no proper ventilation. This poses a threat to you 
and your family’s health. Indoor air quality can be determined by how it affects individuals comfort, and efficiency of work. There is no standard measure of indoor air quality because of high variability of exposure to dust, smoke and there is no scientific standards of air quality in buildings. Therefore, it make us to maintain adequate indoor air quality by providing comfortable temperature, humidity levels and ventilation. This article discusses the ways of improving indoor air quality at appropriate levels.
Before calling professional, check yourself for the sources of pollution – both indoor and outdoor and their source.
Check the sources of pollutant in the indoor and outdoor
The most common air pollutants indoors are – volatile chemicals (hairsprays, cleaning sprays, pesticides), fireplaces, mold, dust mites, fur of pets, building material, asbestos, radon from soil particles, etc. Try to reduce the usage of volatile chemicals and provide maintenance to you home to reduce the dust and mold. Avoid smoking indoor, which contaminates air quality.
Provide mold cleansing maintenance program
Clean condenser and evaporator coils once a moth to remove mold and dust. Mold grows best on these cooling coils as they constantly get moisture. Moreover, coils are exposed to air supply units and hence they get more dust mites and mold. When condenser coils are ignored for many months from being cleaned it may degrade the air quickly.
It is hard to find the presence of microbial growth and clean. You can prevent their growth if you perform proper cleaning from the start. Maintaining from the beginning also cuts down the amount of maintaining time. If you find any one of your family member is affected to respiratory problems then it is better treat the coil with antimicrobial solution to eliminate microbial growth.
It is recommended to clean or replace HVAC systems filters once in a few months. If you find less debris and musty smell from filters, clean it by soaking filters using detergents. When they give foul smell even after thorough cleansing, replace with a new one.
Control optimal temperature and humidity levels
Improper use of HVAC system may lead to increase in humidity levels in the room. When HVAC system is allowed to give over-cooling, it raises the moisture level and causes discomfort. High humidity levels encourage growth of mold and dust in your appliance and air vents. Humidity is one of the reasons for getting respiratory problems in your family members.
Avoid things like over watering plants, fix leaky plumb line, empty the drip pans from dehumidifier, etc. Thus, you need to regulate the cooling requirements for maintaining comfortable air conditions.
Provide proper ventilation
This is an effective method of increasing indoor air quality. Most HVAC systems use forced or mechanical method to ventilate your home. When there is no sufficient fresh air from outdoors, there is a drop in quality of indoor air. To increase ventilation to your home opening windows or operating attic fans is required to remove the indoor air frequently.
When you find exact source of contaminants, discuss with health professionals. When you have clear understanding of the problem like problem of humidity control, insufficient ventilation, you need to call professionals to fix the problem. Keeping track on indoor air quality in your maintenance program will help you reduce damage to equipment, repairs and replacements.
